Answer:
-1/4x(-4/3) = 1/3
You can use caculator. It's really easy
Answer:
Step 3
Step-by-step explanation:
She made her first mistake in Step 3.
This is because 4/7 is actually less than 5/3.
Step 1 and 2 are mathematically accurate.
1/2 is less than 1.
So, since 4/7 is only greater than 1/2 and not greater than 1 as compared to 5/3 which is actually greater than 1, she should have concluded that 4/7 is less than 5/3.
Therefore, Step 3 contains the mistake.
Answer:
y = 4
Step-by-step explanation:
4y 1x
3x 1y
1x=6
18
6+16 =22
18+4= 22
Answer:

For q1 and q2 I have given explanation already.
q3 to multiply radicals the index must be same.
option a . different index. ∛5 √2
option b . same index so √3 √2 = √6
option c. again different index.
Multiply the numbers on the major axis which are 2 and -9 to get -18. Subtract from that 3*4 = 12. So -18-12 = -30. That's the determinant.
